Ok, maybe I am stretching... But I am seeing this happen both internally and externally. When it freezes I will kill the app and then try to restart the stream, often it will not be able to find the Stream device immediately. If I come back in a few minutes later it will work fine - so I am pretty sure the connection between the IOS app and the TiVo stream is being lost. It happened to me just last evening during OOH streaming using a pretty good WiFi network watching Agents of Shield. If you want me to test anything, just let me know.
